The rover has a patch of colored spots that its camera eyes can view. By comparing them to the surface, the rover can tell us the true colors of Mars.
The rovers "back" carries tools to study the Martian environment and look for chemicals that are the building blocks of life. It also carries antennas and hooks that attach to the rovers landing system.
The rovers "body" is high off the ground, so it wont get stuck on rocks. It carries and protects "vital organs" like the robots computer "brains" inside.
The rovers "neck" holds up the cameras to give the rover a human-eye view--that is, for a person about 7 feet tall! The neck also carries a tool to study the weather.
The rovers laser fires to vaporize rocks. The camera can look at the vapor and tell what the rock is made of.
The rovers "eyes" are cameras that take pictures of the Martian landscape, near and far. The rover also has 8 other cameras on its body to help it avoid rock hazards on the ground.
The rovers antennas are like your ears and mouth. They let the rover "listen" to commands from Earth and "speak" to tell us what it finds.
The rover has a "tail" that gives it power. Heat put out from the decay of special atoms (radioisotopes) is converted into electricity.
The rover wont tip over when going over rocks because its "legs" are designed to keep it steady. They rock up and down over the surface, but the rover doesnt!
The rover has six wheels made of a single chunk of aluminum. They have to be "Mars strong" because this heavy rover will land on its wheels.
The rover carries extra drill bits for the rock drill on its robotic arm. When one drill bit wears out, it can reach its robotic arm back toward its "body" and get another one.
The robotic arm reaches out and touches rocks and soil on Mars. The arm can move like your arm, with a shoulder, elbow and wrist to reach interesting rocks.
The rover has a "hand" on the end of its arm that has lots of tools on it that help it study and collect samples of rocks and soil on Mars.
